Splints and nightguards are custom-fabricated appliances designed to protect teeth and supporting structures from the effects of bruxism and occlusal trauma. These appliances are available in hard acrylic, dual laminate, and digitally fabricated designs, including precision 3D printed nightguards. They help reduce tooth wear, alleviate muscle strain, and improve occlusal stability. Fabrication options such as traditional analog workflows and digital design allow for consistent fit, durability, and patient comfort across a variety of clinical indications.
